#CMT# #/CMT# The module for purifying effluent, comprises a tank having a bottom from which a peripheral belt (4) is uplifted, a biological filtration medium placed inside the tank, a unit for supplying effluent to the biological filtration medium, and a unit for recovering the purified effluent through the filtration medium. The bottom of the tank comprises holes for passing the purified effluent through the filtration medium, a base (9) rested on a support (10), and an oxygenation chamber (11). The peripheral belt comprises an internal wall and an external wall. #CMT# : #/CMT# The module for purifying effluent, comprises a tank having a bottom from which a peripheral belt (4) is uplifted, a biological filtration medium placed inside the tank, a unit for supplying effluent to the biological filtration medium, and a unit for recovering the purified effluent through the filtration medium. The bottom of the tank comprises holes for passing the purified effluent through the filtration medium, a base (9) rested on a support (10), and an oxygenation chamber (11). The peripheral belt comprises an internal wall and an external wall delimiting an oxygenation enclosure communicating through the discharge openings laid out in the walls, and an orifice for connecting a pipe. The openings are disposed at an upper surface of the oxygenation enclosure. The passage holes are distributed regularly in the bottom of the tank. The filtration medium comprises a mineral substrate planted with reeds. The effluent supply unit comprises a tank for purifying the effluent, and is equipped with an orifice at its bottom, where the orifice is connected with a rotating joint carried through the pipe. One of the branches of pipe make a balance while the other branch is prolonged through an angularly shifted portion equipped at its end of a double bend, which forms a discharge mouth. The branches of the pipe equipped with discharge mouth are contacted with a thrust bearing. An independent claim is included for a biological effluent purification zone. #CMT#USE : #/CMT# The module is useful for purifying effluent. #CMT#ADVANTAGE : #/CMT# The module is capable of effectively purifying the effluent, and can be easily manufactured. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The diagram shows a purification module. 4 : Peripheral belt 9 : Base 10 : Support 11 : Oxygenation chamber 12 : Recovery unit. |
